This system shows us what Earth may be like in oh, say, 8 billion years
The second closest star system to Earth has at least one planet.
The asteroid 2024 PT5 will orbit Earth for about two months before unmooning us

New software can make maps of solar eclipse paths that include effects of lunar craters and mountains
An asteroid broken up by Earth’s gravity may have given it rings long ago
The binary system has a lot of mysteries to answer for
The ancient passage of a star might have messed up the outer solar system, raining down giant comets
